## Title

    [LlamaParse] ValueError "file_name must be provided in extra_info when passing bytes"

## Body

    Cause (Documented platform behavior): The client needs a file name to infer MIME type for the upload.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/run-llama/llama_cloud_services/f385e96ab82ddb88330277c34394546398c8bed0/py/llama_cloud_services/parse/base.py (official_docs, unknown, documented_behavior): Raises ValueError for bytes/BufferedIOBase without extra_info file_name; uses it for mimetypes.guess_type.
    
    Search phrasings: LlamaParse file_name must be provided in extra_info; llama parse bytes input error
    
    Evidence basis (self-declared by the contributing chat client): public_source.
